我正在使用twitter API来检索我的所有推文。但是,我似乎无法获得“expanded_url”和“hashtag”属性。可以在https://dev.twitter.com/docs/api/1/get/statuses/user_timeline找到此特定API的文档。我的代码如下:
$retweets = 'http://api.twitter.com/1/statuses/user_timeline.json? include_entities=true&include_rts=true&screen_name=callmedan';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $retweets);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curlout = curl_exec($ch);
curl_close($ch);
$response = json_decode($curlout, true);
$tweet_number = count($response);
for($i = 0;$i < $tweet_number;$i++)
{
$url = $response['entities']['urls'];
$hashtag = $response['entities']['hashtags'];
$text = $response[$i]['text'];
echo "$url <br />";
echo "$hashtag <br />";
echo "$text <br />";
echo "<br /><br />";
}
我收到一条错误消息“通知:未定义的索引:实体。”
有什么建议吗?

你应该这样做(如果$ response是一个数组,你必须访问正确的索引):
$url = $response[$i]['entities']['urls'];
$hashtag = $response[$i]['entities']['hashtags'];
$text = $response[$i]['text'];
否则使用foreach:
foreach ($response as $r){
$url = $r['entities']['urls'];
$hashtag = $r['entities']['hashtags'];
$text = $r['text'];

您正在使用整数递增的for循环,但不使用$i
索引。相反,请使用foreach
:
foreach($response as $tweet)
{
$url = $tweet['entities']['urls'];
$hashtag = $tweet['entities']['hashtags'];
$text = $tweet['text'];
echo "$url <br />";
echo "$hashtag <br />";
echo "$text <br />";
echo "<br /><br />";
}
